This 16x20 tiny house plan fits one bedroom, one bathroom, a kitchenette and a living area on a single story. The footprint measures 16'-0" × 20'-0", with 320 sq ft of living space and no porch, deck or patio. It is drawn for a foundation build. It can serve as a small home, guest house or rental unit.
The kitchenette is 4'-9" × 9'-4" and the living area is 8'-11" × 9'-4". The bedroom measures 8'-8" × 8'-4", and the bathroom is 5'-0" × 8'-4". The layout keeps to four rooms, which makes it simple to frame, heat and furnish. Use the room sizes to check bed, sofa and appliance clearances before you build or change anything.

How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Tiny house on a 16 x 20 ft rectangular footprint (320 sq ft), one story, on a foundation: 1 bedroom, 1 bath, kitchenette and living area. No porch, deck or patio.” An AI architect drafted the room program, a layout solver placed every wall and door, and the plan was checked automatically for room sizes, circulation and daylight. The same project produced the PDF sheets, layered DXF, IFC model and 3D model you can download above.
Frequently asked questions
What is included in a 16x20 tiny house plan?
This plan has one bedroom, one bathroom, a kitchenette and a living area on one level. The footprint is 16'-0" × 20'-0" with 320 sq ft of living space. It has no porch, deck, patio or garage.
Can I build this tiny house on a foundation?
Yes, the plan is drawn as a one-story home on a foundation. Foundation type, framing, insulation and utility connections depend on your site and climate. Check them with a local engineer or building department before construction, and confirm whether a small dwelling needs a permit in your area.
How can I customize this plan with AI?
You can describe a change in plain language, such as a different room size or a moved door. The AI then updates the layout while keeping the 16'-0" × 20'-0" footprint unless you change it. Review each result against your local code before you build.
Can I use the plan in CAD with a DXF file?
A DXF file opens in most CAD programs, so you can measure, edit and annotate the plan there. Check the units and scale when you import it. You can then share it with a builder or draftsperson for further detailing.
